Hypothesized to cause arrhythmogenic right ventricular cardiomyopathy when compound heterozygous with G1886S. However, this variant is quite common (2.4% in Europeans), as is G1886S (3.1% in Europeans), and about 1 in 700 are compound heterozygous. This is highly discordant with a disease prevalence of 1 in 2500 to 5000, and notably G1886S is reported in ClinVar as benign. We should consider the original hypothesis disproven.

Reported to cause arrhythmogenic right ventricular cardiomyopathy when compound heterozygous with G1885E, although this finding is weakened after correcting for multiple hypotheses and it is unclear what penetrance such a genotype might have, if it is causal.
